MACHINE OR DEVICE LABELING X- -RAY DENTAL FILMS.

Application filed January 13, 1925, Serial No. 2,144. Renewed August-11,1926.

This 'nvention relates to photographic identifying means, and hasrefert-ince more particularly to means for printing indicia onphotographs which are made by the X-ray or other processes intended formaking photographs of parts of the anatomy, and the said invention asdeveloped is primarily for A use in applying indicia to pictures ofportions of the jaws, including the roots of in teeth, and theapplication of identifying legends to the teeth inordcr that theposition at which the exposure was made may be definitely determined andin order too, that a person viewing the picture may be in- .15 formed atonce as to the particular teeth which are depicted. 1

In studying pictures of the jaws and teeth of human beings, it sometimesbecomesimpossible, after the picture is taken, to identify the side ofthe month which is depicted or the teeth which are shown, and if theroots of teeth have been shown as diseased to an extent that extractionis deemed desirable, it has not always been possible to determine theidentityof the tooth that is shown as diseased at the roots. 1

The invention is of particular importance in enabling-an observer toknow which tooth or teeth are underobservation and to that end, theinvention consists in novel means for applying indicia to the picture ofthe tooth or teeth at the time the picture is taken so that the identifyof the tooth or teeth may be definitely determined. To the end in view,the invention comprises as to details, means for holding the films to beapplied to certain portions of the holder after the exposures are made,or preferably after each exposure the film so exposed is delivered tothe appropriate seat or receptacle of the film holder, and when all ofthe films which are to be exposed for a certain patron have been exposedand placed in the holder, the films so applied to the holder arere-exposed to Roentgen rays which may pass through apertures delineatingthe indicia so that the pictures when finished will display indicia ofthelocation of that portion of the jaw which the photograph depicts.

As a further detail of the invention, it is the purpose of the inventorto produce a device which can be expeditiously employed in order thatfilms may be accurately labeled and indelibly marked to avoidpossibility view, the invention consists in. the details ofconstruction, and in the arrangement and combination of parts to behereinafter more fully set forth and claimed. 7

With the foregoing and other objects in In describing the invention indetail, reference will be had to the accon'ipanying drawings formingpart of this applicatinon wherein like characters denote correspondingparts in the several views, and in. which Figure 2 illustrates aplanview of a plate normally impervious to Roentgen rays, havingperforations for the admission of Roentgen rays; and

Figure 1 illustrates a base with relationto which the said plate coacts.1

In carrying the invention into practice, a

plate A is employed, preferably of metal,

impervious to Roentgen rays, such as lead or the like, the same beingprovided with,

a plurality of series of perforations, the said perforations beingoutlined to depict letters and numbers in the nature of legends, and, ofcourse, these legends will correspond to the terms employed foridentifying all of the natural teeth. The legends are consecutivelynumbered for identification from 1 to 10, or more. The base B with whichthe plate coacts may be made of wood or the the like and it is ofpractically the same dimensions as the plate.

The surface of the block'or base has a plurality of recesses orpocket-like receptacles identified by the reference characters 1, 2, 3',4', 5', 6, 7', 8 9 and 10', etc., the same being intended to receive andretain dental films which areheld'between the perforated plate and thesaid base. The number of recesses is optional but should correspond tothe number of films used in exposing a complete set of teeth. The stem,-ciled characters on each section correspond to and represent thecorresponding segment. of the jaw exhibited on a single film.

Then an exposure is made of, a certain segment of either jaw, that filmis placed in its corresponding receptacle beneath the metal plate, thefilms of the upper teeth being located along the upper edge and those ofthe lower teeth along the lower edge of the device in appropriaterecesses or receptacles. The stenciled characters or indicia denotingthe location of the teeth exposed on the film are placed insuch-position that they are preferably over that portion of the filmhaving the image of the crowns of the teeth when the film lies properlyfitted in its recess or receptacle so that when a complete set or thedesired'part of the set of films is deposited in proper recesses 01'receptacles and the device is exposed to Roentgen rays, only those raystalling on the films through the stenciled characters in the metal platecause a reduction of the silver salts of the film, with the result thatthe characters are blackly imprinted on each developed film across theimages of the crowns of the teeth and the label does not interfere withthe proper reading or interpreta tion of the pathology of the roots.

I claim: I

1. The herein described film identifying device comprising a base havinga plurality of recesses forming seats for sections of film, and a platein'ipervious to Roentgen rays adapted to be superimposed on the base andhaving Roentgen ray adn'iitting openings located in registry with therecesses Tor admitting Roentgen rays to film occupying the recesses.

2. The herein described film identifying device comprising a base havinga plurality of recesses forming seats for sections of film, and a plateimpervious to Roentgen rays adapted to be superimposed on the base andhaving Roentgen ray admitting openings located in registry with therecesses for admitting Roentgen rays to film occupying the recesses, therelation of parts being such that the Roentgen ray admitting aperturesin the plate Will register with the pictures oi? the crowns of the teethimages on the film.

A film identifying device comprising a support for holding a pluralityof films in a predetermined order, and a plate impervious to Roentgenrays and having Roentgen ray admitting openings located in registry withthe respective films for producing indicia thereon.

t. A film identifying device comprising a plate impervious to Roentgenrays, said plate being of su'li'icient area to cover a plu rality offilms placed in the same plane and having portions pervious to Roentgenrays, whereby several films may be simultaneously marked foridentification.

5. The method which comprises exposing a film to Roentgen rays passingthrough an A object to be photographed, thereafter shielding the surfaceof the film from Roentgen rays except for a portion of the surface uponwhich identification marks are desired and then exposing the shieldedfilm to Roentgen rays.

6. The method which comprises exposing a plurality of films to Roentgenrays passing through an object to be photographed, thereafter shieldingthe surfaces of the films from Roentgen rays except for portions of thesurfaces upon which identification marks are desired, and then exposingthe shielded films to Roentgen rays.
